Description
Attempting to change some default values in the gallery_shortcode function. I copied and pasted it into functions.php, changed the values of the 'columns' and 'size' attributes, and then added the filter hook:
add_filter('post_gallery', 'pipp_gallery_shortcode', 10,1 );
Reloading a post with a gallery included causes a segmentation fault:
user@host:/srv/www-apps/folder/wp-content/themes/pipp$ sudo tail /var/log/apache2/error.log
[Wed Dec 19 16:40:06 2012] [notice] child pid 25830 exit signal Segmentation fault (11)
Commenting the add_filter line causes the post to display properly.

I'm going to take a guess here, pipp_gallery_shortcode() calls the post_gallery filter, which calls pipp_gallery_shortcode(), which calls the post_gallery filter, which calls pipp_gallery_shortcode().. etc..
Because there's multiple layers of functions there, PHP's infinite loop protection probably doesn't kick in, remove the filter from your filter and see if that stops it, otherwise, keep debugging your filter and find what does cause it.
